Run thousands of ready-made web scrapers and AI agents from one cloud platform
Over one hundred thousand ready-to-run scrapers and automation tools covering social media, maps, e-commerce, real estate, and general web crawling.
Connect Apify Actors directly to AI assistants and agents so they can search the store, run scrapers, and pull structured results as tool calls.
Managed proxy rotation and unblocking are built into the platform, so scrapers keep working when target sites add defenses.
An open-source crawling library plus Python and JavaScript SDKs for building custom Actors with Playwright, Puppeteer, Selenium, or Cheerio.

Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.
